Chapter 4 Configuring the Cisco MWR 2941 Router Using the CLI
Configuration Sequence
Configuring Global PTP Settings
Step 1 Enter the following commands to configure the global PTP settings:
a. Use the ptp mode command to specify the PTP mode.
Router(config)# ptp mode ordinary
b. Use the ptp priority1 command to configure the preference level for a clock; slave devices use the
priority1 value when selecting a master clock.
Router(config)# ptp priority1 128
c. Use the ptp priority2 command to set a secondary preference level for a clock; slave devices use
the priority2 value when selecting a master clock.
Router(config)# ptp priority2 128
d. Use the ptp domain command to specify the PTP domain number that the router uses. PTP domains
allow you to use multiple independent PTP clocking subdomains on a single network.
Router(config)# ptp domain 6
Note If you want to use PTP redundancy, see Configuring IP Multicast, page 4-64.
Configuring the PTP Mode
Table 4-1 summarizes the PTP mode commands that you can use on the Cisco MWR 2941.
Note If you want to use PTP redundancy, see Configuring IP Multicast, page 4-64.
Table 4-1 PTP Mode Commands
Command Purpose
ptp announce Sets interval and timeout values for PTP announcement packets.
ptp clock-destination Specifies the IP address of a clock destination. This command only applies
when the router is in PTP master unicast mode.
ptp clock-source Specifies the IP address of the clock source. This command only applies
when the router is in PTP slave mode.
ptp delay-req interval Specifies the delay request interval, the time recommended to member
devices to send delay request messages when an interface is in PTP master
mode.
ptp delay-req unicast Configures the Cisco MWR 2941 to send unicast PTP delay request
messages while in multicast mode. This command helps reduce
unnecessary PTP delay request traffic.
ptp enable Enables PTP mode on an interface.
ptp master Sets an interface in master clock mode for PTP clocking.
Note PTP master mode is intended for trial use only and is not for use in
a production network.
